The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Issue summary: When CMS password-based decryption (RFC 3211 / PWRI key unwrap) processes attacker-supplied     CMS data, an attacker-chosen stream-mode KEK cipher can trigger a heap out-of-bounds read in     kek_unwrap_key(). Impact summary: A heap buffer over-read may trigger a crash which leads to Denial of     Service for an application if the input buffer ends at a memory page boundary and the following page is     unmapped. There is no information disclosure as the over-read bytes are not revealed to the attacker. The     key unwrapping function performs a check-byte test as specified in the RFC that reads 7 bytes from a heap     allocation that is based on the wrapped key length from the message. There is a minimum length check based     on the block length of the wrapping cipher. However the cipher is selected from an OID carried in the     attacker's PWRI keyEncryptionAlgorithm with no requirement that the cipher be a block cipher. When an     attacker selects a stream-mode cipher the guard will be ineffective and the allocated buffer containing     the unwrapped key can be too small to fit the check-bytes specified in the RFC and a buffer over-read can     happen. Applications calling CMS_decrypt() or CMS_decrypt_set1_password() (equivalently openssl cms
    -decrypt -pwri_password ...) on untrusted CMS data are vulnerable to this issue. No password knowledge is     required: the over-read happens during the unwrap attempt before any authentication succeeds. The over-     read is limited to a few bytes and is not written to output, so there is no information disclosure.
    Triggering a crash requires the allocation to border unmapped memory, which is unlikely with the normal     allocator. The FIPS modules are not affected by this issue. (CVE-2026-9076)

Note that Nessus relies on the presence of the package as reported by the vendor.
